<FONT ID="LN">7   </FONT><A NAME="7"></A><FONT ID="FormalComment">/**
<FONT ID="LN">8   </FONT><A NAME="8"></A> * The abstract syntax tree (AST) node representing a compilation unit, and so
<FONT ID="LN">9   </FONT><A NAME="9"></A> * the root of the AST.
<FONT ID="LN">10  </FONT><A NAME="10"></A> * 
<FONT ID="LN">11  </FONT><A NAME="11"></A> * It keeps track of the name of the source file, its package name, a list of
<FONT ID="LN">12  </FONT><A NAME="12"></A> * imported types, a list of type (eg class) declarations, and a flag indicating
<FONT ID="LN">13  </FONT><A NAME="13"></A> * if a semantic error has been detected in analysis or code generation. It also
<FONT ID="LN">14  </FONT><A NAME="14"></A> * maintains a CompilationUnitContext (built in pre-analysis) for declaring both
<FONT ID="LN">15  </FONT><A NAME="15"></A> * imported and declared types.
<FONT ID="LN">16  </FONT><A NAME="16"></A> * 
<FONT ID="LN">17  </FONT><A NAME="17"></A> * The AST is produced by the Parser. Once the AST has been built, three
<FONT ID="LN">18  </FONT><A NAME="18"></A> * successive methods are invoked:
<FONT ID="LN">19  </FONT><A NAME="19"></A> * 
<FONT ID="LN">20  </FONT><A NAME="20"></A> * (1) Method preAnalyze() is invoked for making a first pass at type analysis,
<FONT ID="LN">21  </FONT><A NAME="21"></A> * recursively reaching down to the member headers for declaring types and
<FONT ID="LN">22  </FONT><A NAME="22"></A> * member interfaces in the environment (contexts). preAnalyze() also creates a
<FONT ID="LN">23  </FONT><A NAME="23"></A> * partial class file (in memory) for recording member header information, using
<FONT ID="LN">24  </FONT><A NAME="24"></A> * the partialCodegen() method.
<FONT ID="LN">25  </FONT><A NAME="25"></A> * 
<FONT ID="LN">26  </FONT><A NAME="26"></A> * (2) Method analyze() is invoked for type-checking field initializations and
<FONT ID="LN">27  </FONT><A NAME="27"></A> * method bodies, and determining the types of all expressions. A certain amount
<FONT ID="LN">28  </FONT><A NAME="28"></A> * of tree surgery is also done here. And stack frame offsets are computed for
<FONT ID="LN">29  </FONT><A NAME="29"></A> * method parameters and local variables.
<FONT ID="LN">30  </FONT><A NAME="30"></A> * 
<FONT ID="LN">31  </FONT><A NAME="31"></A> * (3) Method codegen() is invoked for generating code for the compilation unit
<FONT ID="LN">32  </FONT><A NAME="32"></A> * to a class file. For each type declaration, it instantiates a CLEmmiter
<FONT ID="LN">33  </FONT><A NAME="33"></A> * object (an abstraction of the class file) and then invokes methods on that
<FONT ID="LN">34  </FONT><A NAME="34"></A> * CLEmitter for generating instructions. At the end of each type declaration, a
<FONT ID="LN">35  </FONT><A NAME="35"></A> * method is invoked on the CLEmitter which writes the class out to the file
<FONT ID="LN">36  </FONT><A NAME="36"></A> * system either as .class file or as a .s (SPIM) file. Of course, codegen()
<FONT ID="LN">37  </FONT><A NAME="37"></A> * makes recursive calls down the tree, to the codegen() methods at each node,
<FONT ID="LN">38  </FONT><A NAME="38"></A> * for generating the appropriate instructions.
